I'm sure he will be fine Sher, as I said before on another thread my Mum suffered an aneurysm, at the age of 73, then had another one 10 days later while she was in the hospital. They didn't do the coiling op (never quite found out why) she was in ITU on life support for 10 days, completely out of it and we were told on numerous occasions to expect the worst as they couldn't stabilise her. She had pneumonia then C Diff, so it was really bad, she was in hospital for nearly 3 months, she had to lie flat for weeks on end so eventually had to learn to walk again BUT she survived :) and miraculously she suffered no after effects at all - no mood swings, speech or mobility problems. She was a little dizzy for 2 days when returning home but the doctor said that could have been the excitement at coming home. She is now nearly 90 still independent in her own home ...... so please don't worry Sher - think positive - sure he will be back to his old self soon :)
